Akari. Put light bulbs. A light bulb illuminates unobstructed white cells in the four cardinal directions (up, down, left, right). A light bulb may not be illuminated by another light bulb. A number means that there are that many light bulbs in the four cells orthogonally adjacent to that cell.
Because Yoshi is bored, he decides to make a blog and post puzzles in it. However, his first puzzle is aesthetically unpleasant, so this Shaymin decides to fix it a bit… “Rated medium!” the Shaymin exclaims.
Employing a very unusual opening allows this puzzle to have both great aesthetics (intended) and a tough-looking puzzle (not intended). Well, good luck. Bifurcation (aka trial-and-error) will easily destroy this apart, but can you get that cool opening?
The opening (R10C4 has to have its bulb below it) is not very unusual ,but nice
That was the implied step from the opening. My intended opening is that the bulb in column 5 can only be in two positions, making the rest empty. The rest of the puzzle is mostly easy.
If i mentioned the implied step,it is obvious I deduced it from the opening that you described.I put it this way:column 5 has to have a bulb somewhere between the H and E blocks.So R10C4 cannot have its bulb in column 5.and the rest of the puzzle is not mostly easy,but extremely easy.
Well you can derive it from trial and error (trying to put a bulb in R10C5 for example), so just precaution.
And I made this puzzle mostly to show that it’s possible to make a puzzle with only 1-givens while at the same time looking somewhat tough and using the exact same black squares layout as the linked puzzle.
